′�?, having a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption in the 295 cm−one phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical concept computations present which the residual absorption from the https://waylonomyyw.blogsuperapp.com/33271009/the-smart-trick-of-baga4se7-crystal-that-no-one-is-discussing
